Nick Cravat, who plays Piccolo, was an acrobat who was teamed with Burt Lancaster before Lancaster became a star. He appears in many of Lancaster's movies. In this one, and in The Crimson Pirate, he plays a mute. The reason was that his thick Brooklyn accent, which he could not lose, would have been wildly out of place in such period pieces.
